$PECIFICATION forming part of Letters Patent No. 354,009, dated December '7, 1886.

A Application filed March 6, 1886. Serial No. 194,326. (No model.)

To all whom it may concern.-

Be it known that l, J 0111s BIERLEY. a citizen of the United States, residing at Newark, in the county of Licking and State of Ohio, have invented certain new and useful Im provements in Heating-Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is a front elevation of the heater as adapted to fit into a fire-place. Fig. 2 is a vertical central section on line as x of Fig. 1. Fig. 3 is a front elevation of the heater as an outstanding stove. Fig. 4 is a detail in vertical section showing the hot-air pipes. Fig. 5 is a horizontal section on line yy of Fig. 1, showing space between the vertical walls of the grate and the sides of the stove. Fig. 6 is a perspective view of the heater as an outstanding stove, jacket off to show shape of stove-walls. Fig. 7 is a top plan View of Fig. 1, the deflecting-hood removed. Fig. 8 is a detail in perspective showing the sloping or inclined side and back of the stove about the vertical grated walls of the fircchamber. Fig. 9 is a detail,in front elevation,ofthe side pieces, to fit between the front edge ofa stove andthe edge of the'fire-place. Fig. 10 is a vertical section on line z .2, Fig. 2, showing the open ends of the air-space between the inclined grated sides and easing. Fig. 11 is a detail in perspective showing lugs on grate in position to be applied in the grated side.

This device belongs to the class called heating stoves, and is equally well adapted for use as an outstanding stove or a tire place heater.

The points of invention relate more particularly to the grate, the grated lining of the firecharnber, the hot-air pipes, the shield between them and the strongest heat of the fire-chamber, means for introducing external air about and around the device and through pip'es which pass through the the chamber, and,

finally, in the general construction of the parts and in their combination, all as will now be more fully set out and explained, reference being had to the accompanying drawings.-

In the drawings, A denotes the hollow inetallic base of the stove, and B the ash-chainber over it, suitably provided with the front door, I), and ash-pan 2). Over this, in front, is the hearth 0, around which at the edge is the removable fender 0, supported by legs a, and at its ends 0 hooked into suitable recesses, d, in the front D of the heater proper. The

small door (2 to the ledge or molding d in the immediate front of the grate E affords means by which to admit or cut off a supply of air at this point. Instead of the present door, there may be a valved opening.

The grate E is inclined downward from near the top of the inside of the molding d nearly to rear of the fire-chamber. It is supported at the front on the ledge or projections e, and at the rear on the lug e, and has at its sides the journals e on which it can be tilted. This operation is very seldom required with this grate, and is accomplished by inserting the poker through the ash-chamber and pushing up the fore part of the grate. In this way the rear part is disengaged from the lug e, and thus the grate moving on its journals will fall down at the rear. The journals or lugs 6 one on each side, as seen in Fig. 5, enter between two of the forward bars in the inclined grated sides and admit of an upward movement of the grate as well as the tilting. The walls of the fire chamber are composed of the grated sides E and back E. These in cline inward slightly from top to bottom from the back and side inner walls, E, of the stove, so that there is left a small air-space between the sides and back of the the chamber and the inner walls of the stove, increasing in widththat is, from side or back to the wall-from the topto the bottom. Opportunity isthus afforded for the circulation of air around the three sides of the firechaniber, between the grated sides and walls, and all accumulation of ashes at or on the sides of the fire-chamber is prevented, because there is afforded at the base of each side and the back a space for the dbris to fall down into the ash-chamber.

By the incline of the grate not only is there afforded special advantage in raking the fire, but in the act of burning the coals are disposed to the verybest advantage for combustion and the natural passing off of the ashes to a very great degree.

In cold weather, when an intense heat is desired, the grate can be filled to the limit of its grated back and sides, and in this way will hold a very large amount of fuel, which, by the opportunity for a free draft all around and through the mass, can be thoroughly ignited through and through, while when only a slight fire is needed asmall amount ofcoal can be kept ignited at the lower and rear end of the firechamber. The side and rear walls, E of the fire-pot casing incline inwardly from the ashchamber up to near the top, and thus afford .the best opportunity for the radiation of heat, as well as give a better shape to the air-chamber formed between it and the outer caslng for the upward flow of the heat, thus not only tending to increase the draft of this current of air, but causing these air currents to be brought more completely into contact with the outside of the fire-pot casing.

Directly above the grate, passing through the chamber of combustion where the heat is the intensest, are the two open-ended pipes F, which extend, respectively, from each outside wallof the upper part of the heater proper on an upward bend or curve and through the upper or crown plate about one-third the distance fromeach side. The special office and advantages of the hot-air pipes will be more fully explainedhereinafter. In orderthatthepipes shall not be too much exposed to the intensity of the heat in the fire-chamber, there is pro vided a shield, Gr, immediately over the rear of the grate, which is held in place bya hook,

g. This shield also acts as an arch or deflector,

to throw out or deflect the heat toward the front of the heater. The volatile products of combustion, passing over this shield, find their way to the exit-pipe H.

The heater at the back and sides is covered by a jacket or casing, I, which so fits about the heater, resting on the top of the base A, inside the rim a, and confined in front by screws and nuts, as to leave an air-space-between it and the walls of the heater. Fresh air admitted bya pipe, 0, from the outside of the house into the chamber a, occupying the entire base of the heater, will find its way up through the holes a in the top edges of said base-chamber, and passing between the jacket and the walls of the heater, will become greatly heated, and, continuing this upward flow, will in part pass through the bent pipes F, and so flow out from the top of the heater,or will pass through the holes in the edge of'the stove,and in this way contribute to heating the room.

An inclined hood, K, perforated in front, is placed on the top of the heater, inside the ledge or rim to. This forms and will serve to deflect the heat into the room. If desired, the bent pipe F may be provided with dampers. To

' insure a close fit in front into the chimneys,

the vertical flat strips L are attached to each side of the heater by any suitable stay at the bottom, and by engagement of the flange at their upper end on the extended edge or side of the hood K, the said upper ends being flanged at Z for that purpose.

To adapt the heater foruse as a stove, it is only necessary to dispense with the strips L. The amount of external air admitted to the base may be regulated at will by the damper in it. The hood K-may be replaced by the perforated cover or top piece, L, when the heater is used as an outstanding stove. Air may be admitted from the room in which the heater is placed through doors A and A in the front and rear, the front one only being used where the heater is used in the fireplace. A

, Having now described my invention, what I consider new, and desire to secure by Letters Patent, is-

1. The combination of the hollow base, the fire-pot casing, and the outer casing, said casings forming an air-chamber communicating with the base and witha heat-deflecting hood perforated in front, and hot-air pipes passing through the side of the stove at one end and directly into the combustion-chamber, directly above the grate, and thence upward through the top of the stove, all as and for the'purposes described.

2. In combination with thestove-casing and the fire-pot,hot-air pipes entering from the side of the casing and passing directly above the grate through the chamber ofcombustion and upward and through the top of the stove, and a heat-deflecting shield in front of that part of said air-pipes which is in the chamber of combustion, all substantially as and for the purposes set forth.

3. In combination with the stove-body, the heat-deflecting hood on its top and the vertical and detachable strips extending from the hood down to the side of the stove to its bottom, whereby said stove can be adapted for from the bottom upward, and theperpendicular external casing, I, substantially as and for the purposes set forth.

6. In combination with a stove-body, as described, the inclined hood 70 on the top, its front wall extended beyond the sides of the stove, and the strip L, flanged at Z, substantially as described.

7. In combination with the fire-pot and its casing, the hot-air pipes F, passing through the sides E of the said casing and out at the top, the rod 9, and the heat-deflecting shield G, held by the rod 9 over the top of the firepot and in front of the said pipes F. substantially as and for the purposes described.

8. The combination of the grate E, inclined from front to rear, and having journals 6", with the grated sides and the front and rear projections, 6 and e, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN BIER-LEY.
